The most frequent usage scenarios for the default graph are:
1. Store metadata about the named graphs
2. Present a union of all named graphs
In case 1, the default graph is privileged and the application relies on its contents actually being accurate. Applications decide which graphs to use or not to use based on metadata in the default graph.
Case 2 is only useful if the named graphs come from â€œcompatible contextsâ€
